Memorize The Quadratic Formula ... In Seconds

Ah ... the venerable Quadratic Formula:

Beginning algebra students everywhere have to memorize this well known formula for solving quadratic equations of the form:

ax² + bx + c = 0.

Many students in early algebra courses lose critical test and quiz points just because they haven't yet fully committed the Quadratic Formula to memory.

I recently came across a brilliant way to do so almost effortlessly ... a memory trick so sublimely ridiculous I couldn't help but think of the famous line: "This is so crazy ... it just might work."

(Sung slowly to the tune of "Pop Goes the Weasel")

"X is equal to negative B

Plus or minus the square root

Of B squared minus 4AC


Over 2A."



Try it!
